A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the rolls. The gap between the rolls is set to the size of product desired, with the realization that the largest feed particle can only be 4 times the gap dimension.

The working principle of the roller crusher machine is that the two toothed rollers rotate in the opposite direction. At this time, the material falling between the toothed rollers will be drawn into the toothed roller under the action of the rotating force, and the toothed roller will crush the material, so as to obtain the material with the ...

The roller crusher is suitable for medium and fine crushing of solid materials, such as coal, coal gangue, coke, limestone, iron ore, quartz stone and sulfur ore in cement, chemical industry, electric power, mining, metallurgy, building materials, refractory materials, coal mines. ... Working Principle. The two rollers have wedge or gasket ...

Double roller crusher working principle The mode of operation of roll crushers is extremely simple, the standard spring rolls consisting of two horizontal cylinders which revolve towards each other. The set is determined by shims which cause the spring-loaded roll to be held back from the solidly mounted roll.

Advantages of Roller Mills. 1. Produce more uniform, fewer fines, and oversized particles when it comes to product quality. 2. Generates less heat (0 – 3 0 C) unlike hammer mill that generates up to 10 0 C. 3. Less moisture loss. 4. Better work environment due to low machine noises level.

The Working Principle of Roll Crusher. Double-roll crusher can be divided into high speed and low speed double-roll crusher according to the revolving speed of roller; According to the installation methods of roller, it can be divided into two kinds: a roller bearing is active, and the other bearings is fixed and two roller bearings are active ...
